Glee did a very good job saying farewell to Cory Monteith. The death was shocking and tragic and glee did a powerful and emotional goodbye. Everyone in the cast was just as shocked as the public was and the goodbye was tear jerking and really helped us move on in a good way.
The loss of a character in a show is hard to handle, the loss of the life for the actual actor is even more terrible. I believe that Glee did the best that they could do to honor his memory and give him a proper send off from a show he helped make so popular.
